Abstract: A light duty liquid detergent with desirable cleansing properties and mildness to the human skin comprising: a sulfonate surfactant, an alkali metal or ammonium salt of a C.sub.8-18 ethoxylated alkyl ether sulfate anionic surfactant, an amine oxide surfactant, an ethoxylated monoalkanol amide, a monoalkanol amide, an alkyl polyglucoside surfactant, and water.

Abstract: A liquid composition useful for selective dissolution of soft metal is disclosed. The composition comprises an organic nitrocompound and a carboxylic acid. The organic nitrocompound, upon exposure to the soft metal, oxidizes the soft metal to form a first soft metal salt. The carboxylic acid, upon exposure to the soft metal salt, react with the first soft metal salt to form a second soft metal salt that is soluble in the composition. Related methods are also disclosed.

Abstract: The present invention provides a solvent mixture comprising n-propyl bromide, a mixture of terpenes and a mixture of low boiling solvents, and a method for cleaning an article (e.g., an electrical, plastic, and metal parts) in a vapor degreaser using the solvent mixture. The solvent mixture of the present invention is non-flammable, non-corrosive and non-hazardous. In addition, it has a high solvency and a very low ozone depleting potential. Thus, using the solvent mixture of the present invention, oil, grease, rosin flux and other organic material can be readily removed from the article of interest in an environmentally safe manner.

Abstract: A stabilized, environmentally-safe solvent mixture and method for using the mixture are provided. The solvent mixture has an ozone depletion factor of less than 0.08. The mixture includes about 80-96.8%, by volume, chlorobromomethane and about 3.2-20.0%, by volume, of a mixture of stabilizers. The mixture of stabilizers includes nitromethane, 1,2-butylene oxide, and 1,3-dioxolane. The mixture of stabilizer inhibits the decomposition of chlorobromomethane. The solvent mixture is particularly effective for cleaning articles having hydrocarbon-soluble contaminants, especially in a vapor degreaser.
